Kirball is a sport played by heraldic and guard trainees meant to serve as military training in the form of a game. It was invented just after the founding of the collegium. The game is played by two teams, and is divided in 4 quarters. Each team has 4 heralds (with their companion), 4 riders (mostly highborn trainees) (may switch horses between quarters) and 4 foot (mostly guard trainees). The ball may be played by hand, foot of hoof or may be whacked with a bat.
